How to specify Unix Makefile generator in CMake?

I was compiling LLVM-7 so I can compile bcc, for there is a command to compile llvm-7 which is

cmake -G <generator> [options] <path to llvm sources>

I have no clue how to specify <generator>. Let us say I want to use Unix Makefiles as generator, what would be the above command and I want the llvm-7 to get installed in /usr/lib/llvm-7/ directory how to make this happen. Does any one know this?

When I tried like

  cmake -G Unix Makefile ./

It cause error

 Makefile ./
CMake Error: Could not create named generator Unix

Put the name of the generator in quotation marks like in

cmake -G "Unix Makefiles" ..

You can omit a space after the -G and use single quotation marks, too.

Clang's documentation contains this in step 3:

cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm

This example shows how to add more options -- by passing flags after -D. To set the install prefix you have to set CMAKE_INSTALL_PREFIX like in

cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=<install_path> ../llvm
